Adjusting the picture quality
(SCREEN)
The SCREEN settings allow you to degauss (demagnetize) the
monitor manually and adjust the picture quality by controlling the
moire and landing.
• If the color is not uniform or the picture is fuzzy, degauss the
monitor (DEGAUSS).
• If elliptical or wavy patterns appear on the screen, cancel the
moire (CANCEL MOIRE).
• If the color is irregular at the corners of the screen, adjust the
landing (LANDING).
The monitor is automatically demagnetized (degaussed) when the
power is turned on.
The screen is degaussed for a few seconds. If a second degauss
cycle is needed, allow a minimum interval of 20 minutes for the
best result.
The CANCEL MOIRE setting is stored in memory for the current
input signal. All other settings are stored in memory for all input
signals.

monitor.
